HOOPER COYNE, OF BALTIMORE, MARYLAND.

SAFETY-RAZOR.

To all whom it may concern:

Be it known that I, HOOPER CoYNn, a citizen of the United States, residing at Baltimore, in" the State of Maryland, have'in-' 5 vented certain new and useful Improvements in Safety-Razors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

, My invention relates to improvements in safety razors, and it consists in the constructions herein described and claimed.

An object of my invention is to provide an improved safety razor adapted to shave smoothly and easily without danger of cutor injury to the face, and provided ".Wit means for preventing the retention and accumulation of the soap and other matters at the cutting edge of the razor.

A further object of my invention is to provide a simple and eflicient safety razor consisting of a guard and a double-edged blade adapted to be clamped in position thereon with either side against said guard and either end forward.

In the accompanying drawings, forminga part of this application and in which similar reference symbols indicate correspondv lng parts in the several views :Figure 1 is a side view of a razor illustrating one embodiment-0f my invention; Fig. 2 is a side viewof my improved razor blade; Fig. 3 is an end view of the blade; Fig. 4: is an edge view of the guard and its attachment to the razor handle; Fig. 5 is an enlarged section on the line 5-5 of Fig. 1; Fig.6 is an enlarged fragmentary perspective view of one of the Wedge-shaped clamping members stamped upwardly fromthe metal guard;

and Fig. 7 is a face view, showing my invention applied to a corn knife. Referring to the drawings, 1 indicates a guard comprising a fiat metal strip formed symmetrically to a longitudinal axis passing through its pivotal connection 2 to the spaced handle members 3,, whereby said guard and its attached blade can be swung into closed; or protected, position within said handle from either side of the latter.

The flat, strip 1 is provided with a pair of integral medially-extending trapezoidal clamping members 4. formed by cutting converging incisions through said strip to form the inclined side edges 5 of said members,

and then stamping upwardlyv the portion of Specification of Letters Patent.

Application filed May 17, 1913.

Patented Apr. 21, 1914;. Serial No. 768,294.

said strip between said converging incisions to space said members'above the upper face .of the strip by upstanding end webs 6 extending along the respective ends of said -members;the ends of said upstanding webs being notched or cut away to provide overa hanging ,clamping portions along the' inclined edges 5 of said members 4. The flat strip 1 is shown provided with longitudinally-extending series of apertures 7 spaced from its side edges and having outer walls 8 inclined inwardly from the front face of said strip.

A flat razor blade 9 isprovided with a pair of opposite V-shaped vcutting edges adapted to lie slightly within the inwardly inclined outer faces 8 of the apertures 7,

whereby said inwardly-inclined faces act to direct the lather and other matter inwardly beneath the lower bevel of said V-shaped cutting edge for preventing the troublesome accumulation of such matter on the guard strip adjacent to the cutting edge of the blade. i

The Hat razor blade 9 is provided with slots 10 arranged symmetrically to the longitudinal and transverse axes of said blade;

each of said slots being formed by a pair of duplicate trapezoidal openings extending symmetrically from a common base This provides an improved and simple construction by which said slots 10 are adapted to receive the trapezoidal members 4: and permit the razor blade to be slipped beneath the free overhanging portions of said trapezoidal members with either end of the blade toward the outer endof the guard strip 1; thereby enabling the blade tabe clamped in position with either cutting edge in cutting relation to the desired edge of said guard strip 1. When the razor blade 9 is thus slipped beneath the overhanging edges 5 of the trapezoidal members 4, the edges of the relatively thin end webs 6 of each of saidclear that my invention provides an improved safety razor, in which the blade can e readily clamped in an eflective shaving position with either face against the guard strip and with either end forward.

I- have illustrated and described preferred and satisfactory.constructions, but changes could be made Within the spirit and scope of my invention.

I claim A safety razor comprising a flat guard platehaving a pair of medially-extending fiat trapezoidal clamping members supported above its upper face by integral spaced end webs terminating slightly within the inclined edges of said trapezoidal memvbers, and a flat razor blade having cutting edges on its opposite sides and provided HOOPE-R COYNE.
